How to use OnTimer in modeless Dialog?
-
// dialog BOOL dlgWait::OnInitDialog(void) { CDialog::OnInitDialog(); SetTimer(1,500, NULL); return TRUE; } void dlgWait::OnTimer(UINT_PTR nIDEvent) { AfxMessageBox("aaaa"); CDialog::OnTimer(nIDEvent); }dlgWait waitDlg; waitDlg.Create(IDD_DLG_WAIT,NULL); waitDlg.ShowWindow(SW_SHOW); // AfxMessageBox("aaaa"); would't display Sleep(10000); /* If change waitDlg.Create(IDD_DLG_WAIT,NULL); waitDlg.ShowWindow(SW_SHOW); to waitDlg.DoModal(); AfxMessageBox("aaaa"); would display */ -
// dialog BOOL dlgWait::OnInitDialog(void) { CDialog::OnInitDialog(); SetTimer(1,500, NULL); return TRUE; } void dlgWait::OnTimer(UINT_PTR nIDEvent) { AfxMessageBox("aaaa"); CDialog::OnTimer(nIDEvent); }dlgWait waitDlg; waitDlg.Create(IDD_DLG_WAIT,NULL); waitDlg.ShowWindow(SW_SHOW); // AfxMessageBox("aaaa"); would't display Sleep(10000); /* If change waitDlg.Create(IDD_DLG_WAIT,NULL); waitDlg.ShowWindow(SW_SHOW); to waitDlg.DoModal(); AfxMessageBox("aaaa"); would display */The problem is because of the Sleep(10000). By doing that, you prevent window messages to be processed, thus your timer message will only be processed after the sleep.

Sleep (10000); will block message pumping.

anyways why you require sleep(10000) here!
